Saving Money: Munchkin

Hey ladies-I started hunting around and then thought perhaps this pool of awesome mamas could help me...I'm searching for an insect repellent that WORKS, that's safe enough to use while nursing and on my three year old-I know that's a tall order! We've tried a few from Vitamin Cottage (one by Jason) that have citronella and they seem okay but not great because you need to use so much and keep reapplying after sunblock or swimmimg. I bought Badger Balm and found it quite annoying to slather myself up with balm and it's hard to get good...
